. Anatomy, descriptive and applied. Anatomy. 1278 THE ORGANS OF DIGESTION PLEXUS BENEATH THE EPITHELIUM solitary nodules of the intestine, and are by some termed the lenticular follicles of the stom- ach. They are not, however, so distinctly circumscribed as the solitary follicles. The pyloric glands {glandulae pyloricae) (Fig. 1019) are the branched tubular glands, and secrete mucus and pepsin. They are placed most plentifullj^ about the pylorus, but between the fundus and pylorus, in the region known as the transitional or intermediate zone, both true gastric glands and pyloric glands are found. Each pyloric gland consists of two or three short tubes opening into a com- mon mouth or duct, the external orifice of which is situated at the bottom of a ervpt. The tubes are wavy, and are of about equal length with the duct. The tubes and duct are lined throughout with simple epithelium, the duct being lined by columnar cells continuous with the epithelium lining the surface of the mucous membrane of the stomach, the tubes with tall, broad, and pale-staining cells, which are finely granular. The pyloric glands branch more frequently, are more curved in direction, and open into deeper foveolae than the true gastric glands (Szymono- wicz). They contain only chief or peptic cells and do not possess parietal cells. These glands, at times, extend into the submucous coat. The cardiac glands are found about the oeso- phageal orifice. They resemble the glands of the oesophagus and are mucous in character. External to the tunica propria of the mucous membrane, and between it and the submucous coat, is a thin stratum of involuntary muscle tis- sue {muscularw mucosae), which in some parts consists only of a single longitudinal layer; in others, of two layers, an irmer circular, and an outer longitudinal. Vessels and Nerves.—The arteries supplying the stomach are the gastric, the pyloric. and the right gastroepiploic branch of the gastroduodenal, the left gastroepiploic and vasa
